Plats: SU, room 306

Abstract: For the ring of integers of a number field, Carlson and
Schlank computed the étale cohomology ring with coefficients in a
finite cyclic group with n=2 elements. In this talk we explain how to
extend this result to arbitrary n and discuss some possible
applications. Joint work with Magnus Carlson.
